Title: Supply voltage warning device for single lens reflex camera
Inventor: NEMOTO KAZUYUKI
IPC: G03B17/18
Filed: 1977-12-28
Abstract: PURPOSE: To warn shortage of a supply voltage with the use of a relatively simple mechanism by preventing a movable reflecting mirror from popping up midway by an electromagnet with the use of a mirror blocking mechanism.  
     CONSTITUTION: When the voltage of a power source battery in a camera becomes lower than a preset level, an exciting current to be fed to the coil 34b of an electromagnet device 32 so that no repulsive magnetic force for separating a movable member 32a including an  electromagnet 33 is generated even if a main switch SW is turned on. As a result, the movable member 32a is kept attracted by the electromagnet so that a retention control member 38 does not automatically move. As a result, when the drive mechanism of a movable reflecting mirror 1 is operated to start the pop-up operation of the mirror 1, the blocking portion 42d of a mirror blocking member 42 is pushed by a mirror driving pin 10a so that the member 42 is turned clockwise about a support pin 45 to have it blocking portion 42c retained by a hook portion 40. Thus, the reflecting mirror 1 is slightly popped up but is interrupted midway of its stroke, and the driving member is also blocked from its rotations thereby to effect no shuttering operation.
